I Application filed April 30, 1901. erial No. 58,295. (No model.)

To all whom it may concern.-

Be it known that I, ADELBERT J. PERRY, a citizen of the United States ofAmerica, whose post-office address is 123 Elmwood avenue, in the cityand county of Providence and State of Rhode Island, have inventedcertain new and useful Improvements in Leaching Apparatus, of which thefollowing is a specification.

My invention relates to an improved mechanism for washing ore, of thatclass of machines which receive the ore in a pulverized state and mixedwith a solution of cyanid, whereby the metal is dissolved by it.

The object of my invention is to introduce a mixture of steam and air inthe pulp,whereby the precious metal receives a quick chem ical action,with the result that considerable time is gained over the methodheretofore employed.

With this end in view my invention consists in the novel constructionand combination of parts hereinafter described, and specifically setforth in the claims.

Figure 1 is a view of my improved ore-separator, partly in elevation andpartly in vertical section, as seen in line a; 00 of Fig. 2. Fig. 2 is atopv plan View of the same as seen in line y y of Fig. 1. Fig. 3 is asectional detail View as seen in line a z of Fig. 2.

Similar letters of reference indicate similar parts in the differentviews of the drawings.

In the drawings, A represents a circular tub having the bottom B and thecentral block 0.

D D are cross-pieces extending across the top of said tub.

E is a vertical tube or pipe properly supported, plugged at the bottom,as seen at a, where it is mounted in the step b, the latter beingfastened to the bottom 13 of the tub by means of the bolts 0 c, as shownin Fig. 1. A bevel-gearF is fastened on the pipe E by the set-screw cland is driven by a bevel-gear G, which is fastened on the shaft H by thesetscrew 6. A circular bearing-plate I is bolted to the cross-pieces D Dat the intersection thereof and is made with an annular channel and acircular central aperture. A bearingplate J, having a tubular hub f andan annular channel, is fastened to the pipe E by the set-screw g, andballs h in the annular channels of the bearing-plates I and J areprovided to reduce friction of the upper bearing in revolving upon thelower bearing.

K and K are pipes having therein the valves j and 2', respectively. Apipe or tube L extends at a right angle therefrom and has an enlargedend 75, with an exterior screw-thread thereon. The pipe L opens into thepipes K and K, as shown in Fig. l.

M is a tubular couplinghaving an inwardlydirected annular flange Zhaving a central aperture and provided with an interior screwthread, bywhich it is engageable with the screw-threaded enlarged end 713 of thepipe L. Th e upper end of the pipe E has the outwardlyextending annularflange m resting upon the inner surface of the annular flange lot thecoupling M, and a packing-ring n is placed between the upper surface ofthe annular flange m of the pipe E and the end of the pipe L, as shownin Fig. 1. It is thus seen that the pipe E passes through the centralaperture of the flanged end of the coupler M and through the centralaperture of the bearingplates I and J and is adapted to be rotated bypower from the shaft H through the beveled gears G F.

Upon the pipe E is the hub N, having four equispaced openings on itssides, as shown in Fig. 2, in each of which openings is inserted a pipe0, and upon the pipe E is also a similar hub P,having four equispacedopenings on its sides, in each of which openings is inserted a pipe Q. Acircular pipe R has branches S to receive the outer ends of the pipes Qand branches T to receive the lower ends of the pipes U,the latterbeingconnected by elbows V to the outer ends of the pipes O. The pipes Q areprovided with a row of small perforations 0, as shown.

. On each side of the four pipes O is mounted a curved and inclinedscraper or blade W, which has its upperend bent over into a tubularform, as shown in detail at p in Fig. 3, and a properly-bentsupporting-piece q, riveted to the blade W, holds said blade to the pipeQ.

An outlet-pipe X opens from the tub A at one side near the bottom and isprovided with a stop-cock 0-.

From a stock-tank (not shown) containing a supply of cyanid solution apipe Y leads and is made to enter the top exposed end of the tub A, asindicated in Fig. 1.

Having thus described the several parts of the said device, I will nowproceed to explain its operation.

The ore to be separated and which has been reduced to a pulverizedcondition is put into the tub A and is indicated as Z in Fig. 1. Theshaft H, rotated by power, imparts, by means of the beveled gears G andF, a rotary movement to the pipe E and the pipes 0,. Q, R, and U,connected therewith, as shown. Steam from a suitable boiler (not shown)is admitted into the pipe K through the valve j and passes through thepipes L, E, O, U,

Q, and R. Hot air from a compressor (not shown) is admitted into thepipe K through the valve 2' and mingles with the steam in said pipes,and this combination of air with steam produces a mixture of steam andair. A cyanid solution from asuitable stock-tank passes throughthe pipeY and mingles with the ore Z, making the same a mass of pulp, and theadmission of a mixture of steam and air is discharged through theperforations 0 of the pipes Q in small jets in the lower portion of themass of ore. As will be seen in Fig. 3, these jets from the perforationso of the pipes Q are directed toward the rear, as indicated by the arrowsin said figure, while the scrapers or blades W are moving in theopposite direction, being supported by the pipes O and Q. This movementof the scrapers or blades .V causes the pulverized ore to move upthereonin the direction indicated by the arrow 25 in Fig. 3, and themixture of steam and air permeates the pulp as the, cyanid solutiondissolves the mass, with the result that a very quick chemical action isobtained upon the precious metal. WVhen the machine has been worked longenough to separate the ore from the gangue, the mass flows out throughthe outlet-pipe X to a filter, (not shown), provided with the usualmeans of precipitation.

' The principle of this invention is to separate and wash out the orefrom the .pulverized mass of material in the tub, so that by discharginga mixture of steam and air under pressure into said mass,together with acyanid solution in the same,givesa chemical action to cause the preciousmetal to quickly separate from the mass, and the thorough mixing andconstant agitation of the mass and permeating it with forcible jets ofamixture of steam and air result in an extraction of the ore more quicklythan by other methods com' monly employed.
